One of the items on the Wiki ToDo list is sorted writes for
checkpoints. The consensus seemed to be that this should be done by
adding hook(s) into the main code, and then a contrib module to work
with those hooks. Is there an existing contrib module that one could
best look to for inspiration on how to go about doing this? I have
the sorted checkpoint working under a guc, but don't know where to
start on converting it to a contrib module instead.
Cheers,
Jeff
